For a few weeks now I've been doing some regular livestreams where I give away some sketches to open requests. Examples can be found here and here. [NSFW on both links]
I don't have a set schedule for these sessions but I try for 2-3 times a week (when I'm in the mood) and try for at least 4 sketches given out, but some sessions have gone up to 8 images. Multiple characters are also welcomed.
However, I only upload a notice journal and image on my FA page. So if you'd like a chance at some free stuff, follow me on FA to receive my notices when I'm LIVE. Hope to see some of you in my next streams. ;)
